Net wrap lifting device

ABSTRACT

A baler includes a body, and a wrap system that is attached to the body. The wrap system is operable to support a roll of wrap material in an installed position. A cover is attached to the body, and is moveable between an open position and a closed position. When in open position, the cover provides access to the wrap system from an exterior location. When in the closed position, the cover encloses the wrap system from the exterior location. The baler includes a lift system attached to one of the body and the cover. The lift system is concealed between the body and the cover when the cover is disposed in the closed position. The lift system is positioned below the cover when the cover is disposed in the open position. The lift system raises the roll of wrap material into the installed position.

RELATED APPLICATIONS

This application is a continuation-in-part application of U.S. patentapplication Ser. No. 16/034,922, filed Jul. 13, 2018, the disclosure ofwhich is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to a baler for accumulating cutcrop material and forming the crop material into a round bale.

BACKGROUND OF THE DISCLOSURE

Round balers accumulate cut crop material, and form the crop materialinto a round bale within a bale forming chamber. Once the bale isformed, the bale must be restrained or bound to maintain is form. Someround balers use a twine that is wound around a circumference of theround bale. Other round balers use a wrap material that is wrappedaround the circumference of the round bale. The wrap material isprovided in a roll of wrap material, and includes a length that issubstantially equal to a height of the round bale. The roll of wrapmaterial is loaded into a wrap system on the baler, and is fed into thebale forming chamber after the round bale has been formed, to wrap theround bale in the wrap material, thereby securing the shape and form ofthe round bale.

The installation position or elevation of the roll of wrap material inthe wrap system may be positioned relatively high, and in some cases,may be above an operator's head. Because of the weight of the roll ofwrap material, some operators have difficulty lifting the roll up to theinstallation elevation. Moreover, there is an industry desire toincrease the size of the roll of wrap material so that the roll does notneed to be changed as often. However, increasing the size of the roll ofwrap material would likewise increase the weight of the roll, whichwould exacerbate the difficulty some operators have in lifting the rollof wrap material up to the installation elevation and into the wrapsystem.

SUMMARY OF THE DISCLOSURE

In one aspect, a baler for use with a netwrap roll is provided. Thebaler includes a frame supported on one or more wheels, a housingcoupled to the frame and at least partially defining a baling chambertherein, a netwrap assembly having a netwrap frame coupled to thehousing and at least partially defining a netwrap chamber, and a loadingdevice at least partially positioned within the netwrap chamber. Theloading device includes a first frame fixed relative to the netwrapframe, a second frame movable relative to the first frame between aframe stowed position and a frame deployed position, a carriage movablerelative to the second frame between a carriage stowed position and acarriage deployed position, and wherein the carriage is configured tosupport the netwrap roll.

In another aspect, a baler for use with a netwrap roll is provided. Thebaler includes a frame supported on one or more wheels, a housingcoupled to the frame and at least partially defining a baling chambertherein, a netwrap cover movable with respect to the housing and atleast partially defining a netwrap chamber therein, wherein the netwrapcover is movable relative to the housing between a closed position, inwhich the netwrap chamber is not accessible from the outside, and anopen position, in which the netwrap chamber is accessible from theoutside, a loading device with a carriage movable with respect to thehousing between a stowed position, in which the carriage is completelypositioned within the netwrap chamber, and a deployed position, in whichat least a portion of the carriage is positioned outside the netwrapchamber, and where the carriage is configured to support at least onenetwrap roll.

According to an aspect of the present disclosure, a baler foraccumulating cut crop material and forming the crop material into around bale is provided. The baler includes a body, and a wrap systemthat is attached to the body. The wrap system is operable to support aroll of wrap material in an installed position. The wrap system isconfigured for wrapping the wrap material around a formed bale in thebaler. A cover is attached to the body. The cover is moveable between anopen position and a closed position. When the cover is disposed in theopen position, the cover provides access to the wrap system from anexterior location. When the cover is disposed in the closed position,the cover encloses the wrap system from the exterior location. The balerincludes a lift system, which is attached to one of the body and thecover. The lift system is concealed between the body and the cover whenthe cover is disposed in the closed position. The lift system isoperable to raise the roll of wrap material, relative to the body, intothe installed position.

In one embodiment of the baler, the lift system is positioned below thecover when the cover is disposed in the open position.

In one aspect of the disclosure, the lift system includes a liftlocation. The lift location is the location from which a vertical forceis applied to one or more components of the baler in order to raise theroll of wrap material. The lift location is positionable at an elevationdisposed above the installed position of the roll of wrap material whenthe cover is disposed in the open position.

In one aspect of the disclosure, the lift system may include a lineactuator having a line. The line extends from the lift location downwardfor engagement with the roll of wrap material. The line actuator isoperable to retract the line in order to raise the roll of wrapmaterial. In one embodiment, the line actuator is an electrically drivenwinch that winds and un-winds the line. In another embodiment, the lineactuator is a manually operated winch that winds and un-winds the line.It should be appreciated that the line actuator may include otherdevices not specifically mentioned or described herein. In one aspect ofthe disclosure, the line actuator is directly attached to the cover. Inanother aspect of the disclosure, the line actuator is directly attachedto the body. In yet another aspect of the disclosure, the line actuatoris directly attached to a jib arm, which is in turn attached to thebody.

In one aspect of the disclosure, the lift system includes a coversupport. The cover support interconnects the cover and the body when thecover is disposed in the open position. The cover support is operable tosecure the cover relative to the body and prevent the cover from closingwhile raising the roll of wrap material.

In one aspect of the disclosure, the lift system includes a liftstructure that is directly attached to the cover. The lift structuredefines the lift location. The lift structure may include, but is notlimited to, a pulley or other similar device capable of redirecting thepath of the line. The line actuator may be attached to either the bodyor the cover, with the line extending around the lift structure anddownward for engagement with the roll of wrap material.

In one aspect of the disclosure, the cover may include a coverstructure, or framework. The cover structure supports the cover, andprovides rigidity and strength for the cover. The cover support and thecover structure are operable to support the cover in the open positionagainst a weight of the roll of wrap material, while raising the roll ofwrap material, without permanent deformation to the cover.

In one aspect of the disclosure, the lift system may include a jib. Thejib is rotatably attached to the body for rotation about a firstvertical axis. The jib rotates about the first vertical axis, on asubstantially horizontal plane, relative to a ground surface. The jibextends from the body to a distal end, with the distal end of the jibdefining the lift location. As such, the distal end of the jib mayinclude the lift structure, such as but not limited to a pulley.

In one aspect of the disclosure, the jib includes a first member and asecond member. The first member is attached to the body for rotationabout the first vertical axis on the substantially horizontal plane. Thesecond member is rotatably attached to the first member for rotationabout a second vertical axis. The first vertical axis and the secondvertical axis are generally parallel with each other. The second memberrotates about the second vertical axis on the substantially horizontalplane, such that the first member and the second member move on the samehorizontal plane. The second member defines the distal end of the jib.In one aspect of the disclosure, the line actuator is attached to thejib. In one embodiment, the line actuator is attached to the secondmember of the jib.

In one aspect of the disclosure, the jib is moveable relative to thebody between a stowed position and an operating position. When the jibis disposed in the stowed position, the jib is nestled against the bodyand out of interference with the cover, so that the cover may bepositioned in the closed position. When the jib is disposed in theoperating position, the jib extends away from the body to present thedistal end of the jib, i.e., the lift location, in a position forraising the roll of wrap material into the installation position.

In one aspect of the disclosure, the jib is rotatably attached to thebody for rotation about a horizontal axis for movement between a firstelevated position and a second elevated position. The first elevatedposition may define the stowed position of the jib. For operation of thejib, the jib is rotated about the horizontal axis into the secondhorizontal position, after which the first member and the second membermay be rotated bout the first vertical axis and the second vertical axisrespectively to position the lift location at the distal end of the jibover the roll of wrap material.

The above and other features will become apparent from the followingdescription and accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS

Before any embodiments of the disclosure are explained in detail, it isto be understood that the disclosure is not limited in its applicationto the details of the formation and arrangement of components set forthin the following description or illustrated in the accompanyingdrawings. The disclosure is capable of supporting other implementationsand of being practiced or of being carried out in various ways.

Those having ordinary skill in the art will recognize that terms such as“above,” “below,” “upward,” “downward,” “top,” “bottom,” etc., are useddescriptively for the figures, and do not represent limitations on thescope of the disclosure, as defined by the appended claims.

Referring to FIGS. 1 and 3-11, a netwrap roll loading device 10 for usewith a baler 14 having a netwrap assembly 42. The baler 14 is configuredto collect crop material 18 from a support surface 22 (i.e., the field),process the crop material 18 into individual finished bales (not shown),wrap the finished bales with netwrap material 26 provided by a separatenetwrap roll 46, and eject the finished and wrapped bales from the baler14. In the illustrated implementation, the baler 14 includes a frame 30,a set of wheels 34 mounted on the frame 30, a housing 38 coupled to theframe 30, and the netwrap assembly 42 configured to store at least onenetwrap roll 46 therein.

For the purposes of this application, each netwrap roll 46 includes asubstantially cylindrical core 50 with a length of netwrap material 26wrapped thereon. The netwrap roll 46 also defines an axial length 54 andan outer diameter 58. As shown in FIG. 2, the netwrap roll 46 may alsoinclude one or more removable handles 60 to aid the user whenmaneuvering the netwrap roll 46.

The frame 30 of the baler 14 is formed from one or more elongatedmembers and includes a front end 62 generally in the form of a tow bar,and a rear end 66 opposite the front end 62. During use, the front end62 of the frame 30 is connectable to a towing vehicle 64 such as anagricultural tractor and the like. The frame 30 of the baler 14 alsodefines a central axis 70 extending longitudinally therethrough and thatis generally aligned with the direction of travel T of the baler 14 (seeFIG. 1). The frame 30 also defines a vertical axis 74 orientedsubstantially perpendicular to the central axis 70 and substantiallyaligned with the force of gravity when the baler 14 is positioned on asubstantially level surface.

The housing 38 of the baler 14 includes a forward covering 78 positionedproximate the front end 62 of the frame 30, and a rear door or croppackage barrier 82 pivotably coupled to the forward covering 78 andpositioned proximate the rear end 66 of the frame 30. Together, theforward covering 78 and rear door 82 at least partially define a balingchamber (not shown) configured to form a bale therein as is well knownin the art. During use, the rear door 82 of the housing 38 is pivotablewith respect to the forward covering 78 between a closed position (seeFIG. 1), in which the rear door 82 encloses the baling chamber andrestricts external access thereto, and an open position (not shown), inwhich the rear door 82 is pivoted away from the forward covering 78allowing the baling chamber to be accessed from the outside. In theillustrated implementation, the rear door 82 is automatically pivotablerelative to the forward covering 78 by a gate actuator (not shown) suchas a hydraulic actuator, electrical actuator, and the like.

The baler 14 also includes a netwrap assembly 42 mounted to the housing38 of the baler 14 and defining a netwrap chamber 94 therein. Duringuse, the netwrap assembly 42 is configured to support at least one“primary” netwrap roll 46 a within the netwrap chamber 94 whose netwrapmaterial 26 is fed into the baling chamber for application onto afinished bale, and one or more “supplemental” netwrap rolls 46 b withinthe netwrap chamber 94 for use after the primary netwrap roll 46 isdepleted (see FIG. 3). In the illustrated implementation, the netwrapassembly 42 is configured to support one primary netwrap roll 46 a andone supplemental netwrap roll 46 b within the netwrap chamber 94.

As shown in FIG. 4, the netwrap assembly 42 includes a netwrap frame 86fixedly coupled to the housing 38, and a netwrap door 90 movably coupledto the netwrap frame 86 to at least partially define the netwrap chamber94 therebetween. The netwrap assembly 42 also includes an operatingassembly 98 at least partially positioned within the netwrap chamber 94,a storage assembly 102 at least partially positioned within the netwrapchamber 94, and the netwrap loading device 10. More specifically, thenetwrap frame 86 is fixedly coupled to the rear door 82 of the housing38 and defines a netwrap plane 100 that is substantially coincidenttherewith. In the illustrated implementation, the netwrap plane 100 hasa substantially vertical orientation such that the netwrap plane 100 issubstantially aligned with the direction of gravity G when the baler 14is positioned on a generally level support surface 22 (see FIG. 6).

While the illustrated netwrap frame 86 is mounted to the rear door 66 ofthe housing 38, in alternative implementations the netwrap frame 86 maybe mounted to any part of the baler 14 including, but not limited to,the forward covering 78, the frame 30, and the like. Still further,while the illustrated implementation includes a single netwrap assembly42 that houses both the primary and supplemental netwrap rolls 46 a, 46b, it is to be understood that the baler 14 may include multiple netwrapassemblies (not shown) configured to store and/or deploy netwrap rolls46 as desired.

As shown in FIGS. 1 and 6-11, the netwrap door 90 of the netwrapassembly 42 is coupled to the netwrap frame 86 and movable with respectthereto between an open position (see FIG. 6), in which the netwrapchamber 94 is accessible from the outside, and a closed position (seeFIG. 1), in which the netwrap chamber 94 is not accessible from theoutside. For the purposes of this application, the netwrap chamber 94 isgenerally defined as the volume of space enclosed between the netwrapdoor 90 and netwrap frame 86 when the netwrap door 90 is in the closedposition (see FIG. 6). In alternative implementations, the netwrap door90 may be mounted directly to the housing 38 of the baler 14. In suchimplementations, the netwrap chamber 94 is generally defined as thevolume of space enclosed between the netwrap door 90 and the housing 38.

In the illustrated implementation, the netwrap door 90 includes asubstantially elongated body including an end wall 106, and a pluralityof side walls 110 each extending from the end wall 106 to define an openend 114. Furthermore, the netwrap door 90 is pivotably coupled to thenetwrap frame 86 such that the netwrap door 90 pivots between the openand closed positions. As such, when the netwrap door 90 is in the closedposition (see FIG. 1), each of the plurality of side walls 110 isgenerally in contact with the netwrap frame 86 or housing 38 to enclosethe netwrap chamber 94 therebetween. In contrast, when the netwrap door90 is in the open position (see FIG. 6), the open end 114 of the door 90is pivoted away from and out of engagement with the netwrap frame 86 andthe housing 38. While the illustrated door 90 is pivotably coupled tothe netwrap frame 86, it is to be understood that in alternativeimplementations that the door 90 may be linearly movable relative to thenetwrap frame 86, include a series of connecting linkages, or even becompletely removable therefrom.

Illustrated in FIG. 6, the operating assembly 98 of the netwrap assembly42 includes the associated machinery and linkages used to rotatablysupport the primary netwrap roll 46 a within the netwrap chamber 94 andfeed the netwrap material 26 located on the corresponding netwrap roll46 a into the baling chamber for application onto a finished bale as iswell known in the art. The operating assembly 98 also defines anoperating volume 118 generally defined as the volume of space occupiedby a netwrap roll 46 when the roll 46 is being supported and manipulatedby the operating assembly 98 (see FIG. 6).

Illustrated in FIG. 6, the storage assembly 102 of the netwrap assembly42 includes the associated machinery and linkages used to support andstore a supplemental netwrap roll 46 b within the netwrap chamber 94independent of the operating assembly 98. The storage assembly 102 alsodefines a storage volume 122 generally defined as the volume of spaceoccupied by the supplemental netwrap roll 46 b when stored by thestorage assembly 102. In the illustrated implementation, at least aportion of the storage volume 122 of the storage assembly 102 isvertically aligned with the operating volume 118 of the operatingassembly 98 such that an axis parallel with the vertical axis 74 canpass through both volumes 118, 122 simultaneously.

Referring to FIGS. 4-11, the loading assembly 10 of the netwrap assembly42 includes a first frame 126 fixed relative to the netwrap frame 86, asecond frame 130 pivotably coupled to the first frame 126, a carriage134 movably coupled to the second frame 130, and a drive assembly 136 tomaneuver the elements 126, 130, 134 of the loading assembly 10 withrespect to one another. During use, the loading assembly 10 isconfigured to receive a netwrap roll 46 positioned outside the netwrapchamber 94 (e.g., positioned proximate the support surface 22; see FIG.11) and convey the collected netwrap roll 46 into at least one of thestorage volume 122 and the operating volume 118 of the netwrap assembly42. More specifically, the loading assembly 10 is adjustable between aretracted position (see FIG. 6), in which the carriage 134 is positionedinside the netwrap chamber 94, and a deployed position (see FIGS. 8 and11), in which the carriage 134 is positioned at least partially outsidethe netwrap chamber 94 and more accessible to the user. In theillustrated implementation, when the loading assembly 10 is in theretracted position, the carriage 134 is at least partially positionedwithin the storage volume 122 of the netwrap chamber 94.

While the illustrated loading assembly 10 is adjustable between aretracted position and a deployed position, it is to be understood thatin alternative implementations the loading assembly 10 may includemultiple deployed positions, each corresponding to a particular locationto which the netwrap roll 46 is to be conveyed (e.g., proximate thesupport surface 22, the operating volume 118, the storage volume 122,and the like).

Illustrated in FIGS. 4 and 5, the first frame 126 of the loadingassembly 10 is fixed relative to the netwrap frame 86 and defines a pairof first mounting points 128 spaced a first mounting distance 130 fromthe netwrap plane 100 (see FIG. 7). Together, the first mounting points126 of the first frame 126 define a first axis of rotation 132 that issubstantially transverse to the central axis 70. In the illustratedimplementation, the distance 130 between the netwrap frame 86 and thefirst mounting points 126 generally corresponds to at least one of thewidth of the storage volume 122 and the operating volume 118. As such,the first distance 130 is generally equal to or larger than the outerdiameter 58 of a netwrap roll 46 intended to be stored therein.

The first frame 126 of the loading assembly 10 includes a pair ofelongated members 138 a, 138 b each having a first end 142 fixedlycoupled to the netwrap frame 86, and a second end 146 opposite the firstend 142 that forms a corresponding one of the first mounting points 126.More specifically, each elongated member 138 a, 138 b of the first frame126 extends outwardly (i.e., rearwardly) from the housing 38 of thebaler 14 in a direction substantially parallel to the central axis 70.

The second frame 130 of the loading assembly 10 includes a pair ofsecond mounting points 150, each pivotably coupled to a correspondingfirst mounting point 128 of the first frame 126. The second frame 130also includes a pair of third mounting points 154, each spaced adistance from the second mounting points 150 and defining a second axis156 that is substantially parallel to the first axis 132. During use,the second frame 130 is pivotable relative to the first frame 126 aboutthe first axis 132 between a stowed position (see FIG. 6), in which thepair of third mounting points 154 (i.e., the second axis 156) are spaceda first distance 158 from the netwrap plane 100, and a deployed position(see FIG. 7), in which the pair of third mounting points 154 (i.e., thesecond axis 156) are spaced a second distance 162 from the netwrap plane100 that is greater than the first distance 158. More specifically, whenthe second frame 130 is in the stowed position, the pair of thirdmounting points 154 are positioned axially between the pair of firstmounting points 126 (i.e., the first axis 132) and the netwrap plane 100(e.g., the first distance 158 is less than the first mounting distance130). In contrast, the pair of third mounting points 154 are positionedaxially further away from the netwrap frame 86 than the pair of firstmounting points 126 when the second frame 130 is in the deployedposition (e.g., the second distance 162 is greater than the firstmounting distance 130).

As shown in FIGS. 7 and 11, the second distance 162 of the second frame130 is sufficiently large so that the pair of third mounting points 154are clear of any obstructions positioned between the mounting points 154and the support surface 22 in a generally vertical orientation (e.g.,generally aligned with the vertical axis 74). While the illustratedimplementation only includes the operating assembly 98 as a potentialobstruction, in alternative implementations such obstructions mayinclude, but are not limited to, a bale accumulator, a trailer, and thelike. In such alternative implementations, the second distance 162 issufficiently large to avoid any obstructions that would hamper thecarriage ability to travel vertically between the support surface 22 andthe second frame 130 when the second frame 130 is in the deployedposition.

In the illustrated implementation, the second frame 130 of the loadingassembly 10 includes a pair of support arms 166 a, 166 b and one or morecross-members 170 extending between and coupled to both support arms 166a, 166 b causing the support arms 166 a, 166 b and cross-members 170 tomove together as a unit. As shown in FIG. 5, each support arm 166 a, 166b of the second frame 130 is substantially “L-shaped” having a first end174 defining a corresponding one of the pair of second mounting points150, and a second end 178 opposite the first end 174 defining acorresponding one of the pair of third mounting points 154. Whenassembled, the second mounting points 150 of each arm 166 a, 166 b arepivotably coupled to a corresponding first mounting point 126 of thefirst frame 126. As such, pivoting the second frame 130 about theresulting joint (e.g., about the first axis 132) causes the thirdmounting points 154 to travel in a substantially arcuate path betweenthe stowed position and the deployed position.

Illustrated in FIG. 5, the carriage 134 of the loading assembly 10includes a body 182 at least partially defining a storage position 186that is sized and shaped to receive at least a portion of a netwrap roll46 therein. During use, the carriage 134 of the loading assembly 10 ismovable relative to the second frame 130 between a retracted position(see FIG. 7), in which the carriage 134 is a first distance 200 from thesecond axis 156, and an extended position (see FIG. 8), in which thecarriage 134 is a second distance 204 from the second axis 156 that isgreater than the first distance 200.

As shown in FIGS. 8 and 11, the carriage 134 is configured to movelinearly with respect to the second frame 130 along a substantiallyvertical path between the stowed and deployed positions. As such, thecarriage 134 is a first vertical distance 300 from the support surface22 in the stowed position, and a second vertical distance 304 from thesupport surface 22 that is less than the first vertical distance 300 inthe deployed position. While the illustrated implementation illustratesthe deployed position of the carriage 134 proximate the support surface22 (e.g., with a second vertical distance 304 close to zero), it is tobe understood that the deployed position may be set to any verticaldistance corresponding to the loading surface being used (e.g., alignedwith a bench, a loading dock, a pallet, and the like). In still otherimplementations, the carriage 134 may have multiple deployed positions,each having a unique vertical height from the support surface 22.

In the illustrated implementation, the body 182 of the carriage 134includes a plurality of support rings 208, each being substantiallyannular in shape and defining an inner diameter 212 that substantiallycorresponds to the outer diameter 58 of the netwrap rolls 46 (see FIGS.5 and 7). During use, the user axially inserts a netwrap roll 46 intothe storage position 186 of the carriage 134 by passing the netwrap roll46 axially through each of the plurality of rings 208 (see FIG. 4). Onceinserted, the netwrap roll 46 and carriage 134 move together as a unit.

As shown in FIG. 5, each ring 208 of the carriage 134 includes a gap 216formed therein to allow the inner diameter 212 of the rings 208 to varyand compensate for changes in the netwrap roll's outer diameter 58.Still further, the gaps 216 are also sized and shaped to allow thehandles 60 of the netwrap roll 46 to pass axially therethrough. As such,when a user inserts the netwrap roll 46 into the storage location 186,the user does not need to remove his hands from the handles 60 for theentire process. In alternative implementations, the carriage 134 mayinclude alternative designs, shapes, or mechanisms to releasably supportat least a portion of a netwrap roll 46 therein.

Illustrated in FIG. 5, the drive assembly 136 of the loading assembly 10includes a first actuator assembly 220 in operable communication withand extending between the first frame 126 and the second frame 130, anda second actuator assembly 224 in operable communication with andextending between the second frame 130 and the carriage 134. Together,the first actuator assembly 220 and the second actuator assembly 224 areconfigured to actively adjust the loading assembly 10 between the stowedconfiguration and the deployed configuration.

The first actuator assembly 220 of the drive assembly 10 includes aplurality of actuators 228, each having a first end 232 and a second end236 movable with respect to the first end 232 to define an actuatordistance 230 therebetween. Once assembled, one of the first end 232 andthe second end 236 of the actuators 228 are coupled to the first frame126 while the other of the first end 232 and the second end 236 arecoupled to the second frame 130. During use, adjusting the actuatordistance 230 of the actuators 228 cause the second frame 130 to pivotrelative to the first frame 126 about the first axis 132 (e.g., at thejoint created between the first mounting points 128 and the secondmounting points 150). More specifically, increasing the actuatordistance 230 causes the second frame 130 to pivot toward the deployedposition (e.g., in direction A) while reducing the actuator distance 230causes the second frame 130 to pivot toward the stowed position (e.g.,in direction B that is opposite to direction A). In the illustratedimplementation, each actuator 228 of the first actuator assembly 220includes a gas spring. However, in alternative implementations,alternative forms of actuation may be used including, but not limitedto, a hydraulic cylinder, a gear train, an electric linear actuator, apneumatic cylinder, biasing members, and the like.

The second actuator assembly 224 of the drive assembly 10 includes apair of pulleys 240 each rotatably mounted to a respective one of thethird mounting points 154 of the second frame 130, a drive motor 244 inoperable communication with and configured to drive the pulleys 240, anda pair of cables 248 each extending between and coupled to a respectivepulley 240 and the carriage 134. During use, rotating the pulleys 240about the second axis 156 causes the carriage 134 to move relative tothe second frame 130 between the retracted position and the extendedposition (described above). More specifically, rotating the pulleys 240in a first direction C causes the corresponding cables 248 to coil ontothe pulleys 240 and shorten the uncoiled length thereof. As such,rotating the pulleys 240 in a first direction C causes the carriage 134to move toward the second frame 130 and the stowed position. Incontrast, rotating the pulleys 240 in a second direction D, opposite thefirst direction C, causes the corresponding cables 248 to uncoil andincrease the uncoiled length thereof. As such, rotating the pulleys 240in the second direction D causes the carriage 134 to move away from thesecond frame 130 and toward the extended position. In the illustratedimplementation, the both pulleys 240 are mounted onto a common shaft 252such that both pulleys 240 rotate together as a unit. This configurationallows the cables 248 to be wound and unwound from the pulleys 240together assuring the orientation of the carriage 134 relative to thesecond axis 156 remains constant.

Illustrated in FIG. 5, the loading assembly 10 also includes acontroller 260 configured to direct and control the operation of theloading assembly 10 during use. The controller 260 includes a processor264, a memory unit 266 in operable communication with the processor 264,and one or more sensors 270, 274 sending and receiving signals from theprocessor 264. The processor 264 is also in operable communication withone or more elements of the baler 14 such as, but not limited to, thefirst actuator assembly 220, the second actuator assembly 224, and auser interface 278. During use, the controller 260 receives one or moresignals from the user interface 278 and the one or more sensors 270,274, inputs the received information into one or more controlalgorithms, and outputs signals to the first actuation assembly 220 andthe second actuation assembly 224 to control the movement of the carrier134 relative to the baler housing 38. More specifically, the processor264 of the controller 260 is configured to send signals to the firstactuation assembly 220 and the second actuation assembly 224 to adjustthe loading device 10 between the stowed configuration (see FIGS. 6 and9) and the deployed configuration (see FIGS. 8 and 11).

The one or more sensors 270, 274 of the controller 260 are positionedthroughout the baler 14 and configured to provide information regardingthe operation and status of the loading device 10. In particular, thecontroller 260 includes a first position sensor 270 configured to detectthe relative position of the second frame 130 with respect to the firstframe 126, and a second position sensor 274 configured to detect therelative position of the carriage 134 with respect to the second frame130. The sensors 270, 274 may be present individually, in plurality, orin combination.

The user interface 278 of the controller 260 is configured to provideand receive information from the user. As shown in FIG. 5, the userinterface 278 includes a remote unit in operable communication with theprocessor 264 and having one or more screens 282 to provide informationto the user, and one or more inputs (e.g., buttons, touchscreens, andthe like) to receive inputs and data from the user. In alternativeimplementations, the user interface 278 may be integrated into the cabof the towing vehicle 64 or fixedly mounted to the housing 38 of thebaler 14.

During baling operations, the netwrap assembly 42 is typically storedwith the loading assembly 10 in the stowed configuration and the netwrapdoor 90 in the closed position (see FIG. 1).

To load a netwrap roll 46 into the netwrap assembly 42, the user pivotsthe netwrap door 90 from the closed position (see FIG. 1) into the openposition (see FIG. 3) to allow exterior access to the netwrap chamber94. In implementations where a powered netwrap door 90 is present (e.g.,an actuator is used), the user may command the netwrap door 90 to openby entering the necessary inputs into the user interface 278. Inmanually operated implementations, the user may manually pivot thenetwrap door 90 between the open and closed positions.

With the netwrap door 90 in the open position, the user may theninstruct the loading assembly 10 to move to the deployed configuration.To do so, the user enters the necessary inputs into the user interface278 instructing the processor 264 to begin the deployment process. Withthe process initiated, the processor 264 sends signals to the firstactuator assembly 220 instructing both actuators 228 to increase inlength. As the actuator lengths 230 increase, the second frame 130pivots about the first axis 132 relative to the first frame 126 in thefirst direction A and toward the deployed position. Simultaneously, thefirst position sensor 270 sends a continuous stream of signals to theprocessor 264 representative of the current angular position of thesecond frame 130.

Once the second frame 130 reaches the deployed position (see FIG. 7),the processor 264 receives a corresponding signal from the firstposition sensor 270 representing the frame's position. The processor 264then processes the signal and instructs the actuators 228 to stop,maintaining the second frame 130 in the deployed position.

With the second frame 130 in the upright position, the processor 264then outputs signals to the second actuator assembly 224 instructing thedrive motor 244 to rotate the pulleys 240 in the second direction D. Asdescribed above, rotating the pulleys 240 in the second direction Dcauses the cables 248 are unwind therefrom increasing the cable'sunwound length. This action, in turn, increases the distance between thecarriage 134 and the second frame 130 and causes the vertical height ofthe carriage 134 to decrease. Simultaneously, the second position sensor274 sends a continuous stream of signals to the processor 264representative of the current distance between the second frame 130 andthe carriage 134.

Once the carriage 134 reaches the deployed position, the processor 264receives a corresponding signal from the second position sensor 274representing the carriage's position. The processor 264 then processesthe signal and instructs the drive motor 244 to stop, maintaining thecarriage 134 in the deployed position and placing the loading assembly10 in the deployed configuration overall. In some implementations, theuser may then adjust the position of the carriage 134 (e.g., increasingor decreasing its vertical height 300) by entering the necessary inputsinto the user interface 278.

With the loading assembly 10 in the deployed configuration, the user maythen load a netwrap roll 46 into the storage position 186 of thecarriage 134. To do so, the user axially passes the roll 46 through eachof the rings 208 of the carriage 134. Due to the carriage's relativelylow position proximate the support surface 22, the user can load thenetwrap roll 46 into the carriage 134 with minimal stress and effort.

Once the netwrap roll 46 is loaded into the storage position 186 of thecarriage 134, the user may then instruct the loading assembly 10 toreturn to the stowed configuration. To do so, the user enters thenecessary inputs into the user interface 278 instructing the processor264 to begin the stowing process. While the illustrate implementationindicates that the stowing process may be initiated by inputs from theuser, in alternative implementations the stowing process may beinitiated by other information including, but not limited to, thedetection of a certain amount of weight in the carriage 134, the tensionwithin the cables 248 exceed a predetermined amount, a certain period oftime has passed, and the like.

With the process initiated, the processor 264 sends signals to thesecond actuator assembly 224 instructing the drive motor 244 to rotatethe pulleys 240 in the first direction C. As described above, rotatingthe pulleys 240 in the first direction C causes the cables 248 to windonto the pulleys 240 decreasing the cable's unwound length. This action,in turn, decreases the distance between the carriage 134 and the secondframe 130 and causes the vertical height 300 of the carriage 134 toincrease. Simultaneously, the second position sensor 274 sends acontinuous stream of signals to the processor 264 representative of thecurrent distance between the second frame 130 and the carriage 134.

Once the carriage 134 reaches the stowed position (see FIG. 7), theprocessor 264 receives a corresponding signal from the second positionsensor 274 representing the carriage's position. The processor 264 thenprocesses the signal and instructs the drive motor 244 to stop,maintaining the carriage 134 in the stowed position.

With the carriage 134 stowed, the processor 264 then outputs signals tothe first actuator assembly 220 instructing both actuators 228 todecrease in length. As the actuator lengths 230 decrease, the secondframe 130 pivots about the first axis 132 relative to the first frame126 in the second direction B and toward the stowed position.Simultaneously, the first position sensor 270 sends a stream ofcontinuous signals to the processor 264 representative of the currentangular position of the second frame 130.

Once the second frame 130 reaches the stowed position (see FIGS. 6 and9), the processor 264 receives a corresponding signal from the firstposition sensor 270 representing the frame's position. The processor 264then processes the signal and instructs the actuators 228 to stop,maintaining the second frame 130 in the stowed position and placing theloading assembly 10 in the stowed configuration overall. As shown inFIG. 6, the stowed configuration of the illustrated implementationcorresponds with placing the netwrap bale 46 in the storage volume 122of the netwrap chamber 94. However, in alternative implementations, theloading assembly 10 may be configured to position the netwrap bale 46 inthe processing volume 118. In still other implementations, the user maybe able to elect on the user interface 278 where the netwrap roll 46 isstored.

With the netwrap roll 46 stored and the loading assembly 10 in thestowed configuration, the user may then pivotably return the netwrapdoor 90 to the closed position and resume baling operations.

FIGS. 12-13 illustrate another implementation of the loading assembly10′. The loading assembly 10′ is substantially similar to the loadingassembly 10 illustrated in FIGS. 1-11. As such, only the differenceswill be discussed herein. All similar features have been given the samereference number with an added prime symbol.

The loading assembly 10′ includes a manual actuator assembly 500′configured to move the second frame 130′ between the stowed position(see FIG. 12) and the deployed position (see FIG. 13). The manualactuator assembly 500′ includes a handle 504′ pivotably coupled to thehousing 38′ and accessible outside the netwrap chamber 98′, a primarycable 508′, a secondary cable 512′, and one or more pulleys 516′ todirect the cables 508′, 512′ during use. The actuator assembly 500′ alsoincludes a pair of elongated members 518′ pivotably coupled to the firstframe 126′ and rotatable together with the second frame 130′ during use.

The primary cable 508′ of the actuator assembly 500′ includes a firstend 520′ coupled to the handle 504′, and a second end 524′ opposite thefirst end 520′. In the illustrated implementation, the second end 524′of the primary cable 508′ forms a loop.

The secondary cable 512′ of the actuator assembly 500′ includes a firstend 528′ coupled to one of the two elongated members 518′, and a secondend 532′ opposite the first end 538′ that is coupled to the other of thetwo elongated member 518′. In the illustrated implementation, the bodyof the cable 512′ extends through the loop formed by the second end 524′of the primary cable 508′.

Each of the elongated members 518′ include a body 536′ having a firstend 540′, a second end 544′ opposite the first end 540′, and a pivotpoint 548′ positioned between the first end 540′ and the second end544′. When assembled, the first end 540′ of each elongated member 518′is coupled to the cross-member 252′ of the second frame 130′ proximateone of the arms 166 a′, 166 b′. Furthermore, the second ends 544′ of theelongated members 518′ are coupled to the first end 528′ and the secondend 532′ of the secondary cable 512′, respectively.

To manually move the second frame 130′ from the stowed position to thedeployed position, the user grasps the handle 504′ and pivots it withrespect to the housing 28′ of the baler 14′. The pivoting motion of thehandle 504′, in turn, pulls on the first end 520′ of the primary cable508′ which causes the second end 524′ of the primary cable 508′ to movein the first direction G.

As the second end 524′ of the primary cable 508′ moves in the firstdirection G, the looped end pulls on the body of the secondary cable512′ causing the first end 528′ and the second end 532′ thereof to moveinwardly toward one another and also move in the first direction G. Thisforce, is transmitted to the second ends 544′ of the elongated members518′ which cause the elongated members to rotate about theircorresponding pivot points 548′. This motion, in turn, is transmitted tothe second frame 130′ which causes the frame 130′ to pivot from thestowed position (see FIG. 12) into the deployed position (see FIG. 13).

To return the second frame 130′ to the stowed position, the userreleases the handle 504′, which allows the system to go slack and allowsthe second frame 130′ to pivot back into the stowed position (see FIG.12).

Referring to the FIGS. 14-20, a baler is generally shown at 620. Thebaler 620 may alternatively be referred to as a round baler 620. Thebaler 620 accumulates cut crop material, and forms the accumulated cropmaterial into a round bale. Generally, the baler 620 accumulates thecrop material in a bale forming chamber, wherein the baler 620 forms thecrop material into the round bale. The manner, process, and/or featuresused to form the crop material into the round bale in the bale formingchamber are known to those skilled in the art, are not pertinent to theteachings of this disclosure, and are therefore not described in detailherein.

The baler 620 includes a body 622. The body 622 may include one or morepanels that form an exterior surface of the baler 620, as well as theframe and other support members that support the panels and othercomponents of the baler 620. Referring to FIG. 15, the baler 620includes a wrap system 624 that is attached to the body 622. The wrapsystem 624 includes a roll 626 of wrap material 628 that is supportedrelative to the body 622 in an installed position. As shown in FIG. 14,the wrap system 624 may further include a second roll 668 of wrapmaterial 628 that is supported relative to the body 622 in a storageposition.

The wrap material 628 includes a width that is substantially equal to,or perhaps slightly larger than, a height of the round bale. The wrapmaterial 628 may include a film, mesh, net, or other material suitablefor wrapping around a circumference of the round bale to secure theshape and/or form of the round bale, and/or to protect the round balefrom moisture intrusion. For example, the wrap material 628 may include,but is not limited to, a plastic film that is wound around thecircumference of the round bale.

The wrap system 624 is configured for wrapping the wrap material 628around the formed round bale in the bale forming chamber of the baler620. As such, the wrap system 624 un-winds the wrap material 628 fromthe roll 626 and feeds the wrap material 628 into the bale formingchamber, where the wrap material 628 is wound around the circumferenceof the round bale. The specific manner in which the wrap system 624un-winds the wrap material 628, feeds the wrap material 628 into thebale forming chamber, and wraps the wrap material 628 around the roundbale within the bale forming chamber is not pertinent to the teachingsof this disclosure, are known to those skilled in the art, and aretherefore not described in detail herein.

Referring to FIGS. 14-20, a cover 630 is moveably attached to the body622. The cover 630 is moveable between a closed position, shown in FIG.14, and an open position, shown in FIGS. 15 through 20. When the cover630 is disposed in the open position, the cover 630 provides access tothe wrap system 624 from an exterior location of the baler 620. Theexterior location may include, for example, a location an operator maystand when loading the roll 626 of wrap material 628 into the wrapsystem 624, or otherwise servicing the wrap system 624. When the cover630 is disposed in the closed position, the cover 630 encloses the wrapsystem 624 from the exterior location. As such, when the cover 630 is inthe closed position, the body 622 and the cover 630 cooperate to form awrap chamber 632 therebetween, wherein the roll 626 of the wrap material628 is positioned when in the installed position. With the cover 630 inthe closed position, the wrap chamber 632 is generally closed or sealedto prevent or limit dust, dirt, debris, and moisture from contacting thewrap system 624, including the roll 626 of wrap material 628.

The exemplary embodiment of the baler 620 includes the cover 630rotatable about a horizontal axis, such that the cover 630 moves in anupward and/or downward motion relative to the body 622, whereby thecover 630 is positioned vertically above the wrap system 624 whendisposed in the open position. However, it should be appreciated that inother embodiments, the cover 630 may rotate about a vertical axis, suchthat the cover moves in a side-to-side motion, whereby the cover 630 ispositioned to a side of the baler 620 when positioned in the openposition.

The baler 620 further includes a lift system 634A, 634B. A firstembodiment of the lift system is generally shown at 634A in FIGS. 14-16,and a second embodiment of the lift system is generally shown at 634B inFIGS. 17-20. The lift system 634A, 634B is operable to raise the roll626 of wrap material 628, relative to the body 622, into the installedposition. The lift system 634A, 634B is attached to one of the body 622and the cover 630. When the cover 630 is disposed in the closedposition, the lift system 634A, 634B is concealed between the body 622and the cover 630, within the wrap chamber 632. The lift system 634A,634B may be accessed by moving the cover 630 into the open position. Inthe exemplary embodiment shown in the Figures and described herein, whenthe cover 630 is disposed in the open position, the lift system 634A,634B is positioned below the cover 630. However, as noted above, if thecover 630 moves to the side when opened, then the lift system 634A, 634Bwould not be positioned below the cover.

The lift system 634A, 634B includes a lift location 636, or a liftpoint. The lift location 636 is the location from which a vertical forceis applied to one or more components of the baler 620 in order to raisethe roll 626 of wrap material 628. When the cover 630 is disposed in theopen position, the lift location 636 is positionable at an elevationdisposed above the installed position of the roll 626 of wrap material628. The lift location 636 is located vertically above the installedposition of the roll 626 of wrap material 628 so that the roll 626 maybe fully lifted into the installed position.

The lift system 634A, 634B may include a line actuator 638 having a line640. The line 640 extends from the lift location 636 downward forengagement with the roll 626 of wrap material 628. The line 640 mayinclude, but is not limited to, a cable, a rope, a chain, a strap, etc.The line 640 may include or attach to a cradle, sling, or other devicefor engaging the roll 626 of wrap material 628. The line actuator 638may include a mechanism capable of retracting and extending the line inorder to raise and lower the roll 626 of wrap material 628. For example,the line actuator 638 may include a winding device that is capable ofwinding and un-winding the line 640 in order to raise and lower the roll626 of wrap material 628. For example, the line actuator 638 mayinclude, but is not limited to, an electrically driven winch or amanually operated winch that winds and unwinds the line 640 to raise andlower the roll 626. In other embodiments, the line actuator 638 mayinclude a linear actuator that moves the line 640 in a linear manner toraise and lower the roll 626. It should be appreciated that the liftsystem 634A, 634B may include a device other than the exemplaryembodiments of the line actuator 638 described herein for raising theroll 626 of wrap material 628.

In some embodiments, the lift system 634A, 634B may include a liftstructure 642. The lift structure 642 may include a device that iscapable of redirecting the path of the line 640. For example, FIGS. 15and 16 show an arrangement of the lift system 634A in phantom thatincludes the lift structure 642 attached to the cover 630. The liftstructure 642 may include a pulley, or other similar device. In oneembodiment, the lift structure 642 may be directly attached to the cover630 to define the lift location 636, such as shown in Phantom in FIGS.15 and 16. In other embodiments, the lift structure 642 may be attachedto a distal end 644 of a jib 646 to define the lift location 636.

Referring to FIGS. 15-16, the first embodiment of the lift system isgenerally shown at 634A. FIGS. 15 and 16 show a first arrangement of thelift system 634A in solid lines, in which the line 640 travels directlyfrom the line actuator 638 to the roll 626. As such, the line actuator638 defines the lift location 636, and not lift structure is used. FIGS.15 and 16 show an alternative arrangement of the lift system 634A inphantom in which the lift system 634A includes the lift structure 642embodied as a pully attached to the cover 630. The first arrangement ofthe lift system 634A shown in solid lines includes the line actuator 638directly attached to the cover 630 and directly defining the liftlocation 636. The line actuator 638 may be extended to lower the line640 for attachment to the roll 626 of wrap material 628 at a lowerelevation. Once the line 640 is attached to the roll 626, the lineactuator 638 may be retracted, e.g., wound, to raise the roll 626 ofwrap material 628 into the installed position in the wrap system 624.The second arrangement of the lift system 634A shown in phantom in FIGS.15 and 16 includes the line actuator 638 directly attached to the cover630, and the lift structure 642 embodied as a pully attached to thecover 630. The pulley of the lift structure 642 defines the liftlocation 636, around which the line 640 is passed to relocate the liftlocation 636 away from the body 622.

Because the winch is attached to and supported by the cover 630 in thefirst embodiment shown in FIGS. 14 through 16, the cover 630 must beconfigured to stay in the open position while raising the roll 626 ofwrap material 628, and must be capable of supporting the weight of theroll 626 of wrap material 628 without deformation. Accordingly, the liftsystem 634A may include a cover support 648. The cover support 648interconnects the cover 630 and the body 622 when the cover 630 isdisposed in the open position, and secures the cover 630 relative to thebody 622 while the lift system 634A is raising the roll 626 of wrapmaterial 628. The cover support 648 may include any structure ormechanism that is capable of maintaining the position of the cover 630in the open position while the cover 630 supports 648 the weight of theroll 626 of wrap material 628. For example, the cover support 648 mayinclude a strut, link, hinge lock, etc., that braces the cover 630 inthe open position relative to the body 622.

Additionally, in order to support the weight of the roll 626 of wrapmaterial 628, the cover 630 may include a cover structure 650. The coverstructure 650 may include a framework, supports, cross members, bracing,etc., which support and provide strength and rigidity to the cover 630.The cover support 648 and the cover structure 650 are operable tosupport the cover 630 in the open position against the weight of theroll 626 of wrap material 628 without permanent deformation to the cover630.

In one embodiment, such as shown in FIGS. 14-16, the line actuator 638may be directly attached to the cover 630 and/or the cover structure650, with the line actuator 638 directly defining the lift location 636.In other embodiments, the line actuator 638 may be directly attached tothe body 622 (not shown), and the lift structure 642 may be attached tothe cover 630 and/or the cover structure 650, such as shown in phantomin FIGS. 15 and 16, to provide the lift location 636. For example, theline actuator 638 may be directly attached to the body 622, and the liftstructure 642 may include a pulley that is directly attached to thecover 630 and/or cover structure 650. The lift structure 642, i.e., thepulley, defines the lift location 636, with the line 640 extendingaround the pulley and downward for engagement with the roll 626 of wrapmaterial 628.

As shown in FIG. 14, when the cover 630 is dispose din the closedposition, the line actuator 638 is disposed or positioned within aregion 670 that is between the roll 626 of wrap material in theinstalled position, and the roll 668 of wrap material in the storedposition. This arrangement advantageously uses the empty space betweenthe rolls 628, 668 to accommodate the line actuator 638 when the coveris positioned in the closed position.

Referring to FIGS. 17-20. A second embodiment of the lift system isgenerally shown at 634B. The lift system 634B includes a jib 646. Thejib 646 extends from the body 622 to a distal end 644, with the distalend 644 of the jib 646 defining the lift location 636. In oneembodiment, the jib 646 is moveable relative to the body 622 between astowed position, shown in FIG. 17, and an operating position, shown inFIGS. 18-20. When the jib 646 is disposed in the stowed position, thejib 646 is nestled against the body 622 in the center region 670 and outof interference with the cover 630 so that the cover 630 may bepositioned in the closed position. When the jib 646 is disposed in theoperating position, the jib 646 extends away from the body 622 andpresents the lift location 636, i.e., the distal end 644 of the jib 646,in a position for raising the roll 626 of wrap material 628 into theinstalled position of the wrap system 624.

In the exemplary embodiment shown in the Figures, the jib 646 isrotatably attached to the body 622 for rotation about a horizontal axis652 for movement between a first elevated position, shown in FIG. 17,and a second elevated position shown in FIG. 18. The first elevatedposition may be associated with the stowed position, whereas the secondelevated position may be associated with the operating position. Asshown in the Figures, the first elevation is lower than the secondelevation. Additionally, the second elevated position positions the liftlocation 636 above the installed position of the roll 626 of wrapmaterial 628. The jib 646 may be rotatably attached to the body 622 inany suitable manner that enables rotation about the horizontal axis 652.Furthermore, it should be appreciated that the jib 646 may be locked orotherwise secured in either the first elevated position or the secondelevated position as needed, so that the jib 646 does not rotate aboutthe horizontal axis 652 while raising the roll 626 of wrap material 628into the installed position, or so that the jib 646 does not move duringtransport when in the stowed position.

The exemplary embodiment of the lift system 634B shown in FIGS. 17-20and described herein includes jib 646 rotatably attached to the body 622for rotation about a first vertical axis 654. Referring to FIGS. 19-20,the jib 646 rotates about the first vertical axis 654, on asubstantially horizontal plane 656, defined by an x axis 664 and a yaxis 666 relative to the ground surface. More specifically, the jib 646includes a first member 658 and a second member 660. The first member658 is attached to the body 622 for rotation about the first verticalaxis 654 on the substantially horizontal plane 656. The second member660 is rotatably attached to the first member 658 for rotation about asecond vertical axis 662. The first vertical axis 654 and the secondvertical axis 662 are parallel with each other. The second member 660rotates about the second vertical axis 662 relative to the first member658 and on the substantially horizontal plane 656 with the first member658. The second member 660 includes the distal end 644 of the jib 646,which defines the lift location 636.

With the jib 646 disposed in the second elevated position, the firstmember 658 and the second member 660 of the jib 646 may rotate about thefirst vertical axis 654 and the second vertical axis 662 respectively,to position the lift location 636 over a wide range of locations. By sodoing, the lift location 636 may be easily positioned directly over theroll 626 of wrap material 628, raised to the proper elevation, and thenswung over into the wrap system 624 and into the installed position. Asshown in the Exemplary embodiment, the line actuator 638 is attached tothe second member 660 of the jib 646, and the lift structure 642 isattached to the distal end 644 of the jib 646, i.e., the distal end 644of the second member 660, to define the lift location 636.

The exemplary embodiment of the baler shown in the Figures and describedherein shows the wrap system 624 and the lift system 634A, 634B locatedat the rearward end of the baler 620. However, it should be appreciatedthat the teachings of this disclosure may be applied to embodiments ofthe baler in which the wrap system, the lift system and the cover arelocated at the forward end of the baler.

While the above describes example embodiments of the present disclosure,these descriptions should not be viewed in a limiting sense. Rather,other variations and modifications may be made without departing fromthe scope and spirit of the present disclosure as defined in theappended claims.
